0b6c5371c0 perf tests attr: Add missing topdown metrics events 
The Topdown metrics events were added as 'perf stat' default events
since commit 42641d6f4d15e6db ("perf stat: Add Topdown metrics events as
default events").

However, the perf attr tests were not updated
accordingly.

The perf attr test fails on the platform which supports Topdown metrics.

  # perf test 17

    17: Setup struct perf_event_attr        :FAILED!

Add Topdown metrics events into perf attr test cases. Make them optional
since they are only available on newer platforms.

Fixes: 42641d6f4d15e6db ("perf stat: Add Topdown metrics events as default events")

1f41873c22 perf tests attr: Add optional term 
Some of the stat events are quite rare to find on common machines (like
front end cycles).

Adding an 'optional' term to mark such events in attr tests. Event
marked as optional will not fail the test case if it's not found in
results.
